The caster is also-applicable to tables, desks, china-closets and other articles of furniture.

The invention has for its object to provide a nove lhand improved caster ot' the kind stated which is simple in construction and which can be. readily adjusted for the purpose statedq In order that the invention may be better understood, reference is hadto the accompanying drawu'ig 1n wluch+ v, j Figure 1 is' a vertical 860M011 of the dcvice, and Fig. 2 is an elevation thereof.

The set screw is not entirely withdrawn from the groove 11 when making the adjustment, but remains therein, so that when the spindle is turned it is caused to travel in the direction of its length. After the adjustment is effected, the set screw is advanced until it firmly bindsthe spindle in the-socket piece and prevents it from turning to disturb theadj ustn lent.
